The Directory, edited by John Rodrigues of Amber Technologies (Concord, Massachusetts), features over 50 pages of descriptions of simulation software packages available in the market today. The 1993 Directory is 25% larger than its predecessor, the 1991 Directory. Over 100 entries are included in the 1993 Directory of Simulation Software. Each entry, listed alphabetically by its name, includes a thorough description of what the package does, the platforms and operating systems on which the package operates, its approximate cost, and the complete address of the source or vendor. The entries are listed in a useful tabular form for easy referral. Especially useful in the 1993 Directory is an alphabetized subject/ applications index cross-referenced to the various packages listed. The Society for Computer Simulation makes it clear that while careful efforts are made to ensure accuracy of the entries, it in no way endorses the packages listed, and the Society has not tested any of the packages. The 1993 Directory of Simulation Software (ISBN 1-56555-015-3) is available for $30/$20 prepaid for non-members/members of SCS at P.O. Box 17900, San Diego, California 92177.

Proposals are invited for tutorials covering subjects of interest to the object technology community. Proposals are solicited at all levels-introductory, intermediate and advanced. Proposals for both advanced and new topics are especially welcome. Tutorials offer a forum for educating professionals and give attendees the opportunity to take an in-depth look at topics of their choice in intensive half, full or two-day sessions. All tutorial proposals will be reviewed by a committee under the direction of the Tutorial chair. Tutorials will be selected on the basis of importance of the topic, expertise of the presenters and the quality and educational value of the material to be presented. Product marketing or selling are inappropriate in this forum. Anyone considering submitting a proposal for a tutorial should request guidelines on tutorial submissions from the tutorial chair. Copies of the proposal must be received by 18 March 1993. E-mail submissions of proposals will be accepted and appreciated. Proposers will be notified of acceptance by 12 May 1993 and the final camera- ready versions of tutorial materials for publication in the tutorial notebooks will be due on 9 July 1993.

While divergent views from panelists often help foster discussion, the main goal this year is to provide substance to conference attendees, not entertainment. Traditionally, panels have consisted of four or five speakers making brief position statements, followed by a discussion driven by questions from the audience. While this format will still be accepted, we are especially interested in proposals for innovative formats that will maximize the attendees' value. Panels will be presented in parallel with the papers. They will be 90 minutes in length, with at least 45 minutes allotted for discussion and debate. Submission Requirements: * Panel title * Brief summary of the key issues to be discussed * Each panelist's name, background and a short description of his/her position on the issues * Proposed panel format with time allotments (90 minutes maximum) * Contact information for the panel moderator (name, affiliation, address and phone number) Panel proposals must be received by 18 March 1993. Proposers will be notified of acceptance by 12 May 1993 and the final camera-ready versions of position papers for publication in the conference proceedings will be due on 20 June 1993. Address submissions and questions to: Sam Adams OOPSLA '93 Panels Chair Knowledge Systems Corporation 114 MacKenan Drive, Suite 100 Cary, NC 27511-6446 Phone: +1-919-481-4000 Fax: +1-919-460-9044 Email: 76450.177@compuserve.com --------------------------------------- WORKSHOPS Workshops are a means for experts to meet and discuss issues with a selected focus in an atmosphere which fosters the active exchange of ideas among researchers and practitioners. They provide a forum for the thrust-and-parry of scientific discourse. Workshops also provide an opportunity for representatives of a research community to coordinate efforts and establish collective plans of action. To ensure a sufficiently small group for effective interaction, workshop attendance is controlled with prospective attendees submitting a short position paper outlining their opinions on an aspect of the workshop topic. Participants are chosen based on the relevance of their position paper to the workshop theme. Workshop presentations are at the discretion of the workshop organizers but all attendees are expected to join in the debate with ample time allotted for general discussion. After the workshop, the organizer(s) will be responsible for reporting to the OOP community via an article in the Proceedings Addendum. Proposals for workshops should be between one and two pages in length, and should contain a description of the topic and intended audience, why the workshop is of interest at this time, and a proposed schedule or preliminary agenda. Proposals should also include the names, affiliations, addresses (postal and electronic), and phone numbers of the organizing committee, which should consist of more than two people knowledgeable in the field but not all at the same institution. Proposals should be submitted as soon as possible but must be received by 18 March 1993. Electronic submissions will be greatly appreciated. Workshop organizers will be notified of acceptance or rejection by 12 May 1993.

At past OOPSLAs, the demonstrations have been well attended and have been an excellent venue for discussing technical aspects of projects and tools. Demonstrations will be selected on the basis of technical merit, relevance to object-oriented programming, novel and interesting features, and feasibility. Presenters should be members of the development or implementation team and will give a technical presentation to a technical audience. Product marketing or selling are inappropriate in this forum. Demonstrations of both commercial and in-house applications, as well as academic and corporate research are sought. In addition to new efforts, we are also interested in "where are they now" demonstrations of projects shown in previous years. Demonstrations should not exceed 30 minutes. Proposals for demonstrations must include a one-page abstract providing the title and description of the demonstration, and the names, affiliation, addresses (postal and electronic), and phone number of the demonstrators. In addition, a description of the technical and hardware requirements for the demonstration is needed. While every effort will be made to provide equipment, demonstrators may be asked to provide their own equipment or to make arrangements for sharing equipment. For details contact the Demonstrations Chair. Three copies of the proposal, including the abstract and technical requirements, must be received by 18 March 1993. Proposers will be notified of acceptance by 12 May 1993. Send submissions to: Bjorn Freeman-Benson OOPSLA '93 Demonstrations Chair Dept. of Computer Science University of Victoria P.O.

And if people can agree on the need to reduce carbon emissions, what would be a fair way to allocate emission quotas? These two questions, so vital in the issue of global climate change, are at the heart of a study completed recently by Yasumasa Fujii. The study recently won for him one of three coveted Peccei Scholarships awarded by IIASA for outstanding work in its Young Scientists Summer Program. While participating in the 1990 YSSP, Fujii developed a novel approach to the problem of climate change and international burden-sharing. The result is a working paper that offers fresh insights into the question of historic contributions to the CO2 buildup, and the problem of how to allocate future emissions fairly. The scheme is founded on a principle of rigorous equity: all people born from the onset of the Industrial Revolution to the year 2100 would have an equal carbon emission quota, regardless of where or when they lived. Fujii adopted this principle in part to address the concerns of developing nations, which point out that they have enjoyed few of the fruits of industrialization -- the main cause of the CO2 buildup -- yet they are now being asked to share the burden of carbon cutbacks. Under Fujii's scheme, present and future generations of Africans, Asians, and Latin Americans would inherit the unspent carbon quotas of their 19th- and 20th-century forerunners. But his calculations indicate that this inheritance may be of little benefit to poorer nations, given trends in population growth. Fujii concluded that continued high population growth in the developing world would quickly overwhelm any emission credits from past generations, leaving developing regions in the 21st century with per capita quotas not significantly greater than for most of the developed world. His study, like other energy-related work underway at IIASA, reflects mounting concern about the consequences of changes in the atmosphere. Devastation of forests and crops, flooding of islands and sea coasts, great storms and great droughts -- these are some of the predicted upshots of climate change brought on by manmade changes in the atmosphere. Skeptics point out that all projections of climate change, let alone its consequences, will remain suspect until science better understands the complex systems that regulate climate. However, some scientists contend that waiting for that understanding entails a colossal gamble. In 1986 the World Meteorological Organization concluded: "We are conducting one giant experiment on a global scale by increasing the concentration of trace gases in the atmosphere without knowing the consequences." The main greenhouse gases put into the atmosphere by human activity are carbon dioxide (CO2), methane, chlorofluorocarbons, nitrous oxide, and ozone. CO2 is the biggest problem, accounting for about half the addition to natural global warming potential. And the biggest source of increased CO2, as well as nitrous oxide, is the burning of fossil fuels for energy. The 1990 report of the Intergovernmental Panel on Climate Change estimated that energy use accounts for 46% of mankind's yearly greenhouse- gas emissions, and predicted that the figure will rise to 65%. Clearly, control of global warming will depend on control of energy use. The most obvious form of control - burning fewer fossil fuels - would yield great benefits in areas unrelated to global warming, notably in the control of pollution. Part of the solution lies in greater energy efficiency. Another part lies in a shift to energy sources that emit fewer greenhouse gases. But projections at IIASA and elsewhere indicate that even if these measures and others are vigorously pursued, the buildup of greenhouse gases will continue. The driving factor will be population. Various projections indicate that high growth rates in the developing world, especially Africa, will cause the world's population to double or even triple within 50 years. Leaders of many poor countries insist that economic and social development take priority over other issues, which in practice may mean a growing consumption of energy. The question then is not whether atmospheric greenhouse gases will increase, but how quickly and by how much. In light of this, international agreements to limit carbon emissions could be vitally important. Fujii has developed a simplified mathematical model of atmospheric concentration. The resulting calculations lend support to the complaints of developing nations that current levels of carbon emissions do not reflect historic responsibility for the CO2 problem. For most of the past two centuries Europeans and North Americans have consumed vast quantities of fossil fuels. By contrast the peoples of most developing countries consumed insignificant amounts. Recent statistics, however, show a dramatic rise in fossil fuel consumption in some industrializing regions, notably in countries such as China that have turned to coal as a source of cheap and available power. Thus Western Europe currently accounts for about 16% of the carbon added annually to the atmosphere by the burning of fossil fuels, but Fujii's calculations suggest that it is responsible for 26% of the rise in atmospheric CO2 levels since 1800. By contrast, Asia (including China, a major coal user) currently accounts for 19% of annual emissions, but is responsible for only 9% of the historic buildup. His calculations of per capita emissions show an even greater regional imbalance. Since 1800 North Americans have been by far the greatest emitters of carbon, averaging about 3.7 tons per person per year. Western Europeans have been the third largest contributors, averaging about 1.2 tons per person per year. Current consumption in North America is about 5.3 tons per person per year; in Western Europe 2.3 tons. Fujii's calculations also underscore the fact that industrialization came late to the USSR and Eastern Europe. In 1990 the USSR emitted 3.3 tons of carbon per person per year, making its peoples the second-highest emitters of carbon after North Americans. But since 1800 the peoples of the USSR and its forerunners have averaged about 0.9 tons per year, or a quarter as much as North Americans. As for Asia, Africa, and Latin America, none has historical averages above a quarter-ton per person per year. They currently average carbon emissions of 0.3 to 0.6 tons per person per year. Fujii calculates that Asia, Africa, and Latin America would have average quotas through the next century of 1.5 to 1.7 tons per person per year, a negligible difference from the quotas of 1.4 to 1.7 tons calculated for Western and Eastern Europe, the former Soviet Union, and Japan. The exception was North America, where the quota calculations reflect generations of high energy use. Future North Americans could redress the region's carbon account balance only by cutting average emissions to 0.5 tons per person per year, about a tenth of the current rate in the region. The comparison is equally stark when calculated as a yearly rate of change from current emission levels. North Americans would have to cut per capita emissions between now and 2100 by 7.4% each year. By comparison the annual cuts required for other industrialized regions would be significantly smaller; for the former Soviet Union, 1.5% per year; Eastern and Western Europe, 1.0%; Japan, less than 0.5%. Africa, Asia, and Latin America would be able to triple and quadruple their current per capita emissions to levels comparable to averages in the industrialized world outside North America. Fujii readily acknowledges weaknesses in his methodology. His carbon cycle model is based on relatively simple mathematics, but as his study notes, "The real carbon cycle must have non-linear characteristics and be desperately complicated." His calculations of quotas are based only on emissions from fossil fuel consumption, neglecting emissions from biotic sources. They also neglect potential efforts to mitigate carbon buildup, including reforestation or CO2 abatement technologies. And his rigid criteria of equity overlook complex and deep-rooted linkages among energy use, geography, and social history. In summary, Fujii's study underscores some important points. (1) North Americans bear the largest historical responsibility for the present carbon problem. (2) Some regions currently emitting high amounts of carbon per capita, notably the former USSR, Eastern Europe, and Asia, have contributed relatively little historically to the problem. (3) Historic rebalancing of carbon emissions would require only modest annual per capita cuts in emissions by most industrialized regions, but radical cuts by North America. (4) Expected high rates of population growth in developing regions would quickly overwhelm any emission credits inherited from past generations, leaving them with CO2 allocations no greater than in most developed regions. * * * ------------------------------ Date: Tue, 5 Jan 93 10:10:13 GMT From: mcleod@Sdsc.Edu Subject: December '92 Calendar SIMULATION-RELATED CALENDAR OF EVENTS A component of E-S3 John and Suzette McLeod, Editors E-mail "mcleod@sdsc.bitnet" Based on the December 1992 issue of SIMULATION the technical journal of the Society for Computer Simulation * NOTE: An updated calendar will be sent to you every month or so, in which past events will be deleted, and new events added.
